Add support for calling SMCCC_ARCH_SOC_ID which is used by Linux soc_id driver for printing information about manufacturer and also chip version and silicon ID code. SOC revision is directly mapped to chip ID code. And SOC version is composed from manufacturer ID based on JEP-106 with chip_id which contains bits mapped to CPU register 0xffca0044 platform bits which differentiate between silicon, qemu and other emulated platforms. Function description is available at docs/getting_started/porting-guide.rst. Change-Id: I1f19e1973593897e71b39244dbdbceb6bd0e8a07 Signed-off-by: Michal Simek <michal.simek@amd.com>
